Per 9to5 Mac, a set of black and white schematics of what are purported to be the next-generation iPhone have been discovered. The schematics show assorted new features of the device such as the redesigned speaker grills, and repositioned earphone jack and FaceTime camera, exact display dimensions are still unknown. The plans show what appears to be the next-generation iPhone front glass with enough room for the much rumored, roughly 4-inch display.

On Wednesday, new schematics have surfaced via Cydia Blog that show a diagonal opening of just slightly over 4-inches. The designs also show the repositioned FaceTime camera above the earpiece.

Although calculations of the display show an opening less than .1 of an inch over 4-inches, the display could likely measure a flat 4-inches diagonally as the front panel is typically slightly larger than the display itself.
